.CORNER-PIECE FOR SCREEN-FRAMES.

To all whom 'it may concern:

Be it known that I, GILBERT E. FERRY, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Corner-Pieces forScreen-Frames, of which' the following is a specification.

This invention relates to improvements in corner pieces for screens orsinlar frames, and has for its object to provide corner pieces of thisclass having features of construction whereby the cost of manufacturemay be reduced, but wherein a strong and convenient structure may beproduced for use in efect-ually securing together the terminals of thevertical and horizontal strips of the frame.

Metallic sheets are generally employed in the manufacture of cornerpieces of this class; they are formed so that they envelop more or lessof the end portions of the strips. In their manufacture, the requiredforms are generally cut from integral sheets, and a loss of material hasresulted on account of the comparatively extensive and angular formsrequired, when cutting the sheets. The herein described corner pieces,by reason of their construction are very convenient for mounting uponthe ends of the strips, and may be manufactured from small portions ofwaste sheets or cuttings of no particular value for other purposes,whereby the cost of production is lessened, and an article is provided,convenient and eective for the purposes required.

With these objects in view the invention discloses a novel combinationand arrangement of parts, as described herein, pointed out by theappended claims, and as illustrated in the accompanying drawing, itbeing understood that changes in form, size, proportion and minordetails may be made within the scope of the claims without de partingfrom the spirit of the invention or sacrificing any of its advantages.

In the drawing, Figure 1 is a perspective view showing the terminals ofa horizontal and vertical strip of an ordinary screen frame, beforebeing secured together. Fig. 2 is a view of the same parts shown in Fig.1, wit-h corner pieces mounted thereon em bodying my invention. Figs. 3and l are `perspective views illustrating the construetion, separately,of the corner pieces shown Specification of Letters Patent,

Application filed October 18, 1909.

in Fig. 2. Fig. 5 is a plan View of the upper side of a horizontal stripand the upper end of a vertical strip, the corner pieces being mountedthereon. Fig. 6 is a plan view of the lower side of a horizontal strip,the vertical strip being in section, and illustrating the employment offlanges, a part of a window frame, and a tongue usually employed inconnection with slidable screen frames being added and in section.

Referring now to the drawing for a more particular description, numerals7 and 8 indicate, respectively, horizontal and vertical strips of ascreen frame or other like device, and as is well known, grooves 9 aregenerally formed in the outer sides or faces of the vertical strips,extending their entire length.

At 10 is indicated a support or part of a window frame, a longitudinalprojection, ridge or tongue thereon being indicated at 11, and inpractice, when the parts of a screen frame have been assembled andoperatively mounted, said screen frame is slidable, the tongues engagingwithin the grooves.

In order that the terminals of the horizontal and vertical strips may beeffectively secured together, I provide the corner pieces indicated at12 and 13. They are each L- shaped7 and may be constructed to advantageof sheet metal. Each has a flat body portion 14 adapted to have aseating upon the side of a horizontal strip; also each has a flat bodyportion 15 integral with and disposed in the plane of body-portion 14,adapted to have a seating upon a side of a vertical strip. Body portions14 of the L-shaped corner pieces are provided with transverse 'upper andlower flanges, indicated respectively at 16 and 17. They are disposedsubstantially at right angles to these body portions, and are adapted tohave seatings, respectively upon the upper and lower sides or faces ofthe horizontal strips. Body portions 15 of the corner pieces areprovided with flanges 18 and 19 disposed substantially at right anglesto said body portions. Flanges 19 are adapted to have seatings upon theinner sides of the vertical strips. Flanges 18 are disposedsubstantially at right angles to body portions 15 and may have seatingsupon the outer sides of the vertical strips adjacent to grooves 9, andthey may have inwardly extending wings 2O tallic strips dis osedsubstantially parallel with said bo y portions l5, and are adapted tohave seatings upon the oppositely-disposed walls 21 of said grooves 9.

In practice, the terminals of the horizontal and vertical strips of ascreen frame may be effectively held together by use, singly, of eitherof the L-shaped members 12 or 13, and it is not necessary that both beused. Where they are used in this manner, the members are secured uponthe same side of the screen frame, the opposite side remaining blank.Where thin material is employed, however, it is an advantage to use bothmembers 12 and 13 conjointly. The preferred construction is to provide awidth for flanges 16 equal to the space between the sides of the strips,as best shown in Figs. 2 and 5, these flanges having reduced or cut awayportions to provide the inclined edges 22 intermediate flanges 18 andtheir free longitudinal edges 23, in which instance, flanges 16 mayoverlap, as plainly shown in said Fig. 2. This construction however,while adding materially to rigidity and strength as compared withlianges of less width which could not overlap, is not important. Butwhere thin material is employed they may be constructed and disposed ina manner to overlap to advantage. It will be noted that flanges 16, asshown do not obtrude upon groove 9. It will be understood that cornerpieces of this class must be so constructed that tongue 11 may have anunobstructed seating within and throughout the entire length of saidgroove.

In operation, body portions 15 of the L- shaped corner pieces are firstseated upon the terminal of a vertical strip 8, and it will be held bymeans of flanges 1S and 19, also it will be seen that longitudinal wings20 provide an additional holding means. I employ holdin members toconnect the L- shaped memflrvers to the strips, as brads or nails 23driven into the sides of strip 8 through openings 24 of body-portions15. Horizontal strip 7 is then inserted between body portions 14 and ispushed forwardly until its front end makes yContact with the verticalstrip, and at this time it is held between flanges 16 and 17, and pinsor nails 25 and 26 may be driven into the horizontal strip through t-herespective openings 27 and 28, whereby the terminals of the horizontaland vertical strips will be securely fastened together. I

It will be seen that the herein described corner pieces may beconstructed from meof small size, as compared with integral structureswhich envelop both sides of the horizontal and vertical strips. Also theparts as shown and described may be readily assembled, and may beconveniently secured.

Longitudinal wings 20 provide metallic portions which may make contactwith longitudinal tongue l1, so that the screen may slide with lessfriction, and they provide an increased degree of rigidity for saidflanges. I do not claim any novelty in the screen frame shown in thedrawing. The herein described means are simply for securing theterminals of frame strips where they meet at right angles to form acorner of the frame.
